Instructions: Input data into the blue boxes for your material and punch & die configuration. This
estimates the tonnage required to complete a 90° bend.Click here for Material Strength Reference Table. |

DISCLAIMER: Actual bending force is affected
by many factors such as friction between the material and the die,
material thickness, material strength variations, rolling direction of the
steel, work hardening and other parameters. This estimator calculates a
force representative of the press brake requirement for air bending. Sizing
of a machine or available die width should allow for up to 20% additional
capacity. Pacific Press makes no guarantee of actual force required to
make a bend in a specific part. |
